Ted Kaczynski led a self-sufficient life in the Montana forests, without electricity or running water and with limited use of technology. After seeing the landscape around his cabin being destroyed for the construction of a highway, he started sending self-made bombs to different targets, including computer store owners, airline companies, and university professors. His letter bombs, sent between 1978 and 1995, killed 3 people and injured 23. Ted Kaczynski, known as the Unabomber, in an image used by press agencies.
